[Q]Data and MMS help for Tmobile on unlocked i337 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hello, I have an unlocked i337 and i am currently using it with Tmobile. Almost everything seems to be working fine with it except a few hiccups and I was hoping someone could help me figure out what is wrong.
1. After I unlocked it using the service method I was getting 4G (HSPA+) speeds most of the time and sometimes 4G LTE speeds. The data speeds were great and I was receiving incoming and outgoing text messages fine. But while I was able to make calls just fine I was unable to receive any calls. Anyone who dial my number would go straight to voicemail. After messing around a bit with the phone my solution was to us *#2263# and select "WCDMA and GSM only". Once I did that I lost the LTE speeds but I was able to still maintain HSPA+ and receive phone calls.
Any solution to this without sacrificing LTE?
2. While I can can receive MMS messages fine it takes a really, really long time to send one(hours) and sometimes it doesn't send at all. My data is HSPA+ and pretty fast and I have excellent service in my area so I can't figure out what is wrong with it. I have been using Viber and tango to get around it.
Any idea what I can do?
3. I have to make frequent trips to a hospital for my son who has a congenital heart defect(so we are there for 6-7 hours at a time). In the hospital, the service is very poor but they offer free wifi. My previous phone was a tmobile Note 2 and it had wifi calling so I was able to get service while there.
Can I flash a tmobile S4 ROM to get wifi calling to work? Will I lose my unlock or brick my phone if I flash it? Should I use the MOD that enables
all AWS bands first?
thanks in advance for any help you guys can give.

Hero, have to choose: Data/3G or voice calls, HTC reinvet the 90's!

Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

i have sprint as well and when someone calls you when youre running hybrid, you should not miss calls. you will get disconnected from the internet when someone is calling though

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

yeah... mms is great. i use it to send items that i wish to purchase etc.
What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?

Domestic Voice, Domestic Data

Recently Today my EVO 3D flashed to Metro will no longer Roam. Its either in service or No service. Usually it will roam on near by Verizon Tower and im able to still send texts just not make calls, which im fine with that.
Any Idea what is causing that.
And exactly what does enabling or disabling Domestic Voice/Data do on metros service.
WTF, as soon as i hit enter the phone goes right into roaming Analog B/A So now its working. Once i enabled the Domestic voice and data it started to roam. Hmm. Still need info if you can help

No Calls come in if on Sprint LTE network and browsing internet

I have new S5. NO CALLS come in if are on LTE/CDMA network browsing internet and someone is trying to call you in the same time. Sprint had me changed to CDMA and in that case calls do come through. Anyone else has this problem?

As i understand, the problem is if 4G network doesn't support voice over LTE (4G is only for data). And when you receive call, the phone that is on 4G network, it must switch to 3G. And at this switch error happens. that's why you don't get call, that's why i get SMS with notification of missed call.
Been testing between network modes "LTE/WCDMA/GSM" and "WCDMA/GSM".
When i am on "WCDMA/GSM", i have no problem..

G900V on T-Mobile / MetroPCS

Hello everyone.
A few days ago I got a Galaxy S5 Verizon (G900V).
The phone is GSM and unlocked.
I went to MetroPCS and had them activate it. Of course, they
gave me the BS about it being a Verizon phone, but the activation still worked.
Calls and texts work fine.
However, the 4GLTE signal is always very low, and sometimes drops to 3G where the 3G icon is greyed out basically saying I have no data access.
The online time I have good signal is when I mess with the Network modes and ServIceMode options enough to turn the 4GLTE/3G icon info an "E" (for EDGE data), but that is extremely slow.
Is there a way to fix this?
I have root access.
Thanks
I'd also like to mention that I wouldn't mind having HSPA+ if that's all I can get. I just need a stable signal.
Please someone help.
Anyone?
How did they switch it for you? I have a s5 through Verizon and I have service through metro pcs. But I can't get it to switch over to my s5. Can you help me? I'm like 300 miles away from the closest metro pcs so I am doing all of this on my own. I'm a noobie

No mobile data during calls on G930U

I just flashed G930U firmware (Oreo RG3) on my verizon S7 and overall I'm much happier with my phone. But, sometimes when placing a call with a strong LTE signal, the mobile data disappears and becomes unavailable until the call is completed. The strange thing is that it only happens 50 percent of the time. I've changed my network settings from global to LTE/ CDMA but that doesn't fix the problem. Is this a known issue with the "u" firmware? Or is it perhaps only prevalent on this particular version I installed? Any feedback is appreciated! Thanks!

I don't think that the devices stay connected to 4G LTE while on the actual phonecall as it uses the data maybe for the enhanced calling?
I noticed the same change in connections on my Verizon s7 and att s4. It varies and changes during initiated outbound calls or once a call is incoming. Even seconds before incoming calls I see it drop from 4g LTE down to no internet at all. Then without wifi connected during those ones you can't get online while in call. It depends on phone Carrier like Att, Vzw, and even tracfone brand devices.
It usually cuts back to 3g or H+ and even old Edge/gprs or worse, 2g speeds until the calls are complete. Then regular 4g LTE will come back if your phone is working. This is all from personal experience so please don't take what I say over the other developers who might be able to explain what it is happening a little better.
Hope this helps either way!
P.s- It also probably depends on how strong your signal is to determine what speed you will drop down to during calls. Exp. 4g lte,4g,H+,H,3g,2g,edge,gprs,wap.
